DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments of the invention, which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. It is apparent that the described embodiments are some but not all of the embodiments of the present invention. Based on the disclosed embodiments, persons of ordinary skill in the art may derive other embodiments consistent with the present disclosure, all of which are within the scope of the present invention. Further, in the present disclosure, the disclosed embodiments and the features of the disclosed embodiments may be combined or separated under conditions without conflicts.

Often, there are often two methods to input emojis: a user may browse over a list of emoji characters and select a specific emoji to insert; or, when a user types in words in a certain language, the input method searches through the emoji mapping table in real-time to find a matched emoji, and then pops up the emoji for the user. However, when a user types in words, emojis often pop up, thus interrupting the information input process performed by the user. The disclosed emoji input method and device thereof are directed to at least partially solve the problem set forth above and other problems.

The present disclosure provides an improved emoji input device and method thereof. The disclosed emoji input device and method thereof may not only solve the problem that emojis often pop up when a user types in words, but may also improve the input efficiency of a user by detecting a user operation that starts an emoji conversion function and later converting input words to emojis when necessary.

FIG. 1 illustrates a flow chart corresponding to an emoji input method. As shown in FIG. 1, the emoji input method may include an operation that detects whether a user starts an emoji conversion function (step 100).

Specifically, a control, such as a switch button or an icon for the emoji conversion function may be designed in a graphical user interface that shows input emojis. A conversion detection module may be configured to determine whether the user has triggered the present control to start the emoji conversion function. Further, by calling an interface of an operation system or registering a touch monitor event of the operation system, whether the user starts the emoji conversion function may be detected.

The emoji input method may also include an operation that acquires user input words and executes word segmentation to obtain keyword candidates (step 110). In the present disclosure, a keyword may refer to a word that is frequently used, a word with specific meanings, or a word with certain attributes.

Specifically, the interface of the operation system may be called to acquire the user input words. Further, by calling the built-in interface of an operation system, the acquired user input words may undergo word segmentation to obtain at least one word entry. Each word entry may be a keyword candidate used to match an emoji.

The emoji input method may further include an operation that inputs emojis corresponding to at least partial keyword candidates based on the mapping relationship between regularly updated keywords and emojis (step 120).

Specifically, an electronic device may have a local keyword list. The keywords in the list may be popular vocabulary used in a preset period of time, namely, vocabulary with a relatively high input frequency. The keywords may be obtained by performing big data analysis of chatting records and online articles. The locally stored keywords in the electronic device may be regularly updated via a server. An electronic device or a server may also preset the mapping relationship between keywords and emojis. One keyword may corresponds to one more emojis. One emoji may correspond to one or more keywords. Often, the electronic device may temporarily store and regularly maintain the mapping relationship between keywords and emojis. For example, the electronic device may delete, empty, add or update the mapping relationship between keywords and emojis. In operation, the electronic device may regularly update the mapping relationship between the cached keywords and emojis via the server.

Keyword candidates may be obtained by segmenting user input words, and each keyword candidate may be matched in the preset keyword list, respectively. If the matching is successful, namely, a specific keyword is included in the keyword list, then the keyword may be converted to an emoji; if the matching is unsuccessful, namely, the specific keyword is not included in the keyword list, then the keyword may not be converted to an emoji for future input. After the keywords that may be converted to an emoji are determined, the keywords determined from user input words may be converted to emojis for input.

FIG. 2 illustrates a flow chart corresponding to another emoji input method consistent with embodiments of the present disclosure. As shown in FIG. 2, the emoji input method may include an operation that establishes the mapping relationship between keywords and emojis (Step 200).

Specifically, the keywords may be obtained by performing big data analysis of chatting records and online articles. First, the electronic device may request a keyword list from the server and locally store the keyword list. Every time when an electronic device starts or an application for inputting emoji launches in the electronic device, the electronic device may request the latest keyword list from the server, and regularly update the locally saved keywords in the electronic device. Meanwhile, the electronic device or the server may preset the mapping relationship between keywords and emojis. Often, the electronic device may temporarily save and regularly maintain the mapping relationship between keywords and emojis. For example, the electronic device or a user using the electronic device may delete, empty, add or update the mapping relationships between keywords and emojis. In operation, the electronic device may regularly update the mapping relationship between cached keywords and emojis via the server. The user may also add more keywords through the electronic device and simultaneously add the corresponding emojis.

In some embodiments, the emoji input application may map keywords and emojis based on the attributes of the emojis and the keywords. For example, a key work “smile” may be mapped to an emoji showing a smile based on the meaning of the emoji and the keywords. In some embodiments, the emoji input application may maintain a number of different mappings between the keywords and emojis. For example, a key work “smile” may be associated with emoji A in a first set of mappings and may be associated with emoji B in a second set of mappings. The first set or second set of mappings may use emojis with certain characteristics, such as emojis of a certain color, or of a certain cartoon character, etc. When a user selects the emoji to be used in subsequent steps, the user may first select which set of emoji mappings to use and then select the specific emoji to be used.

The emoji input method may also include displaying a switch control that starts emoji conversion function on a word input screen (Step 210). For example, the control may be a switch button or an icon that starts emoji conversion function on the input method interface.

The emoji input method may also include an operation that detects whether the user starts the emoji conversion function (step 220). Specifically, the disclosed operation may include detecting a trigger action by the user on the preset control that starts the emoji conversion function. In operation, during the process that the user inputs words via a word input interface, whether the emoji conversion function is started or not may be determined by detecting the trigger action by the user on the preset control. By calling the interface of an operation system or registering a touch monitor event, the user operation that starts the emoji conversion function may be detected. For example, when a click on the switch that controls the emoji conversion function is detected, the current status of the switch may be obtained, and if the current status shows disabled emoji conversion function, the emoji conversion function may be started.

The emoji input method may also include an operation that acquires user input words and executes word segmentation to obtain keyword candidates (step 230).

Specifically, the interface of the operation system may be called to acquire the user input words. Further, by calling the built-in interface of an operation system, the acquired user input words may undergo word segmentation to obtain at least one word entry. Each entry may be a keyword candidate used to match an emoji. In operation, the built-in word analysis system in an Android or IOS operation system may be applied to execute word segmentation for user input words to obtain keyword candidates. For example, acquired user input words “I love star” may be segmented into three entries of “I”, “love”, “star” by calling the interface provided by the operation system, and the three entries of “I”, “love”, “star” may be selected as keyword candidates.

The emoji input method may further include an operation that inputs emojis corresponding to at least partial keyword candidates based on the mapping relationship between keywords and emojis (step 240).

Keyword candidates may be obtained by segmenting user input words, and each keyword candidate may be matched with words in the preset keyword list, respectively. If the matching is successful, namely, the specific keyword is included in the keyword list, then the keyword may be converted to an emoji; if the matching is unsuccessful, namely, the specific keyword is not included in the keyword list, then the keyword may not be converted to an emoji for future input. After the keywords that may be converted to an emoji are determined, the keywords determined from user input words may be converted to emojis for input.

In operation, based on the mapping relationship between keywords and emojis, there may be two conditions when inputting emojis corresponding to at least partial keyword candidates. Still, the three keyword candidates “I”, “love”, “star” may be used to illustrate the specific process of inputting emojis corresponding to at least partial keyword candidates based on the mapping relationship between regularly updated keywords and emojis.

In the first condition, the specific process of inputting emojis corresponding to at least partial keyword candidates may include determining the emojis corresponding to the disclosed keyword candidates based on the mapping relationship between regularly updated keywords and emojis. Further, for keyword candidates with more than one corresponding emojis, the keyword candidates may be highlighted. Based on the highlighted keyword candidates selected by the user, a list of emojis corresponding to the keyword candidates may be displayed. Further, based on the list selected by the user, the keyword candidates selected by the user may be replaced with user selected emojis from the list.

Each keyword candidate may be matched in the preset and regularly updated keyword list. For example, if a keyword “love” exists in the keyword list, then the successfully matched keyword candidate may be “love”. For the successfully matched keyword candidate “love”, the emoji corresponding to “love” may be determined based on the mapping relationship between regularly updated keywords and emojis. Assume there are two emojis corresponding to the keyword “love”, the input keyword candidate “love” may be highlighted. In operation, displaying methods like highlighting, box-in, underline and bolding may be applied to clearly show the keyword candidates with more than one corresponding emojis.

For example, FIG. 3 illustrates a screen displaying the keyword candidate 301 “love” with corresponding emojis. As shown in FIG. 3, based on the mapping relationship between regularly updated keywords and emojis, more than one emoji corresponding to the keyword candidate 301 “love” may be determined, accordingly, the keyword candidate 301 “love” may be underlined.

Later, a user click on a word input interface may be detected. When a click on a highlighted keyword candidate is detected, the keyword candidate selected by the user may be determined, and simultaneously, a list of emojis corresponding to the highlighted keyword candidates may be displayed in a preset location within the word input interface, as shown in FIG. 4. Specifically, in FIG. 4, the highlighted keyword candidate is 301 “love”, and emojis corresponding to 301 “love” may be an emoji 302 or an emoji 303. Further, based on the user click on an emoji 302 or an emoji 303 from the emoji list, one emoji corresponding to the keyword candidate 301 “love” may be selected to replace the keyword candidate 301 “love”. If the user clicks on the emoji 302, the emoji 302 may replace the keyword candidate 301 “love”, and the user input information with the keyword candidate “love” being replaced is illustrated in FIG. 5.

In the second condition, the specific process of inputting emojis corresponding to at least partial keyword candidates may include determining the emojis corresponding to the keyword candidates based on the mapping relationship between the regularly updated keywords and emojis. Further, for keyword candidates with one or less than one corresponding emoji, the keyword candidates may be replaced with the emoji corresponding to the keyword candidates.

Each keyword candidate may be matched in the preset and regularly updated keyword list. For example, if a keyword “star” exists in the keyword list, then the successfully matched keyword candidate may be “star”. For the successfully matched keyword candidate “star”, the emoji corresponding to “star” may be determined based on the mapping relationship between regularly updated keywords and emojis. Assume there is only one emoji corresponding to the keyword “star”, the keyword “star” may be replaced with the corresponding emoji, and the user input information with the keyword candidate “star” being replaced is illustrated in FIG. 6.

The emoji may be an image with a unique code. The server may save the image corresponding to the emoji, and each emoji may have a unique code. When the input interface displays the user input emoji, the electronic device may acquire the attribute of an emoji from the server according to the code of the emoji. The attribute of the emoji may at least include the image link of the emoji. Further, based on the image link of the acquired emoji, the image data of the emoji may be read and displayed. The emoji may be saved in a form of image, thus showing a better platform flexibility in a word-storing library compared to existing technologies. For example, the emojis with the same code may have the same displaying effects in different operation systems.

The mapping relationship between keywords and emojis may be stored locally in the electronic device, or may be stored in the server. Often, the electronic device may temporarily save the mapping relationship between keywords and emojis, and when the electronic device launches, or when the word input software launches, or at other moment, the electronic device may request the mapping relationship between updated keywords and emojis from the server to update the local mapping relationship. Via the mapping relationship between the locally cached keywords and emojis, the input of emojis may also be realized when the internet connection is not smooth or when there is no internet connection, thus saving the internet dataflow. By regularly updating the mapping relationship between the locally-cached keywords in the electronic device and the emojis, embodiments of the present disclosure maintain the diversity and novelty of the emojis, and improve the user experience.

FIG. 7 illustrates a flow chart corresponding to an emoji input method consistent with the present disclosure. As shown in FIG. 7, the emoji input method may include an operation that detects whether the user starts the emoji conversion function (step 700). The emoji input method may also include an operation that acquires user input words and segments the words to obtain keyword candidates (step 710).

Further, the emoji input method may include an operation that inputs emojis corresponding to at least partial keyword candidates based on the mapping relationship between regularly updated keywords and emojis (step 720).

After an operation that inputs emojis corresponding to at least partial keyword candidates based on the mapping relationship between regularly updated keywords and emojis, the emoji input method may also include obtaining the attribute information of the user input emojis. When the attribute information indicates that the disclosed emoji carries relevant information, the preset location of the emoji may display a preset identity.

The emoji input method may include obtaining the attribute information of the user input emoji (step 730). For example, in the process of word input in an instant messaging software, after obtaining the user input information that contains regular words and emojis, the instant messaging software may confirm the codes of the emojis contained in the input information, send the codes of the emojis to the server, and request the attribute information of the emojis from the server.

The server may store an emoji code list. The code list may include codes of emojis and attribute information of each emoji. The attribute information of an emoji may include a download link of the emoji, whether the emoji carries an identity with relevant information, and a link to relevant information. The link to the relevant information may be an Uniform Resource Locator (URL), or a memory address on the server. The link to the relevant information on the server may be the memory address or the uniform resource locator of the relevant information pre-searched or provided by the server according to the keyword corresponding to each emoji.

In one embodiment, the attribute information of an emoji may also include the keyword corresponding to the emoji. The instant messaging software in the electronic device may acquire the attribute information of the emoji and search relevant information in a communication log according to a specific keyword, or a phase consists of the specific keyword and ordinary symbols adjacent to the emoji, or the code of the emoji. The link to the searched relevant information may be used as the link to relevant information.

The emoji input method may include displaying the preset identity in the preset location of the emoji when the attribute information indicates that the disclosed emoji carries relevant information (step 740).

For the acquired attribute information of the user input emoji, first, the image download link of the emoji may be read, and the image data of the emoji may be downloaded via the download link and displayed. Further, whether the emoji carries an identity of relevant information may be determined according to whether the attribute information carries an identity of relevant information. If the emoji carries an identity of relevant information, the preset location of the emoji may display a preset identity. In operation, the preset location may be at the top right corner, the top left corner, or the lower right corner, and the preset identity may be an underline, a circle, or a color lump. FIG. 8 illustrates a screen displaying an emoji with a preset identity. As shown in FIG. 8, a circle 802 at the top right corner of an emoji 801 may indicate that the emoji 801 carries relevant information. By triggering the emoji 801, relevant information of the emoji 801 may be further reviewed.

When the attribute information indicates that the disclosed emoji carries relevant information, the method after displaying the preset identity in the preset location of the emoji may include determining the emoji displayed with a preset identity triggered by the user, and obtaining and displaying relevant information carried by the emoji.

The emoji input method may include determining the emoji triggered by the user that displays the preset identity (step 750). After the instant messaging software displays the user input information, the method may detect a trigger operation by the user on the emoji with a preset identity from the user input information. For example, the method may detect a clicking operation by the user on the emoji 801.

The emoji input method may include acquiring and displaying relevant information carried by the emoji (step 760). When the emoji with a preset identity triggered by the user is determined, the instant messaging software may acquire the link to the relevant information from the attribute information of the emoji 801. When the link to the relevant information is the memory address on the server or a local memory address, the instant messaging software may read relevant information from a designated address of the server, and create a child window or a floating window on top of a currently displayed window to display the relevant information read from the server, as illustrated in FIG. 9.

When the link to the relevant information is a URL, the instant messaging software may create a child window or a floating window on top of the currently displayed window, a browser software may be launched to read the page content of the URL and display the page content on the child window or the floating window.
